ide: constify struct ide_dma_ops

* Export ide_dma_exec_cmd() and __ide_dma_test_irq().

* Constify struct ide_dma_ops.

* Always set hwif->dma_ops to &sff_dma_ops in ide_setup_dma()
  (it is later overriden by ide_init_port() if needed) and drop
  'const struct ide_port_info *d' argument.

While at it:

* Rename __ide_dma_test_irq() to ide_dma_test_irq().
